Can be quickly and easily converted

The electronics in the key is safe for everyone is replaceable and completed in 5 min.

To change the actual key bit from the original one either needs a very small impact of about 2 mm in diameter, or one makes do with an iron drill and 250 g Machinist's hammer (so I've converted).

The transponder for the immobilizer is rebuilt with the board and does not require specially glued.

Good value as far as perfectly fine.
